Patent GB-1277991-A (GB)
Title: A resonistor
IPC: H03B5/30
Filed: 1970-05-14
Abstract: 1277991 Generating oscillations INTERNATIONAL BUSINESS MACHINES CORP 14 May 1970 [29 May 1969] 23369/70 Headings H3B and H3T [Also in Division H1] An oscillator has a mechanically resonant semi-conductor bar clamped at one end, a heating element (to deflect the bar) being formed integrally at one side of the bar near its clamping point and a piezo-resistive bridge being formed in the adjacent free part of the bar. The heating element, the bridge, and the resistors diodes and transistors of the feedback/control system of the oscillator are formed in the intrinsic silicon bar by integrated circuit techniques. The system is so arranged that during operation at "normal" mechanical amplitude a fixed current is supplied to the heater 15 for one half of the oscillatory cycle only, but should the amplitude exceed a predetermined level the system additionally supplies current to the heater during that part of the other half cycle subsequent to its amplitude first exceeding the predetermined level. As shown, the output of the deflection sensitive piezo-resistive bridge 14 is fed to a differential amplifier 16, thence to a squarer 21 and via an OR gate 22 to the heater 15. The output of the differential amplifier is also fed to a peak detector 25 set to give an output on the negative half cycle if a limit control voltage is exceeded. The peak detector and the squarer 21 provide the inputs to a bi-stable circuit 23 the output of which provides the other input to the OR gate 22 so that the heater 15 may be energized (with the same polarity) during part of the other half cycle of the squarer during excess amplitude periods.

Title: Door operating systems
IPC: E05F15/20
Filed: 1973-05-16
Abstract: 1418190 Fire doors WON-DOOR CORP 16 May 1973 [23 May 1972] 23448/73 Heading A5A [Also in Divisions E2 and H2] A fire door 26 is moved to close an opening 12 by a mechanism comprising a pulley drive system 38 operated through an electromagnetic clutch 42, reduction gear 40 and motor 44 under the control of an electronic control system 46 which ensures closing of the door in response to a fire-warning signal and, by time-controlled means, causes the door to repeatedly open and close subsequent to the initial closing to enable persons in the building, of which the door is a part, to escape. System 46 is connected to a D.C. source by lines 48 and 50 which feed motor 44 in series with a switch component 54 and a current sensor 56 and through a reversing switch assembly 58 by means of which the motor is controlled for either closing or opening movement of the door. Actuation of switch assembly 58 is effected through a drive control component 60 to which drive-producing signals are fed from a pair of control logics 62 and 64 and these are triggered into operation by signals supplied from a gate circuit 66, though manual control is provided by a pair of switches 68, 70. Switch component 54 is normally energised whenever switch assembly 58 is supplying current to motor 44 and a load control component 72 is connected to switch assembly 54 to de-energise the motor momentarily during logic-controlled operation. Such operation is initiated by a signal from a fire detector 74 passing through a latching switch component 76, and an automatic repetative close logic 78 that generates operating pulses for transmission by gate circuit 66 to close logic 62. Whenever a signal is fed initially to logic 62 a signal is fed also to disable logic 80 through which a signal is fed to load control component 72 to render assembly 54 temporarily insensitive to motor overload. During logic-controlled operation the movement of the door will be momentarily checked if it meets an obstruction and when closed the operation is stopped by limit switch 82 which also triggers a timer component 84 which determines the time of sequential logic-controlled opening of the door before the door is finally closed and fire extinguisher component 86 is triggered into operation.

Title: Improvements in processes and apparatus for treating heavier hydrocarbons
Filed: 1928-08-20
Abstract: 321,929. Jensen, C. A., (Jenkins Petroleum Process Co.). Aug. 20, 1928. Hydrocarbons, cracking.-In a continuous process for producing gasoline or other light oils by cracking heavier hydrocarbons, the stock mixed with adsorbents is charged by a pump 19 into the head of a reflux dephlegmator 23 where it mingles with residues from the cracking process and passes through, two or more tubes 17, into a longitudinal drum 1 connected by front and rear sluiceways 2, 3 with transverse drums 4, 5 and a bank of tubes 6. Cracking conditions are maintained in the drum 1 which is not extraneously heated, by rapidly circulating the oil from the tubes 6 to the drum 1 by means of a propeller 8 driven by a motor 9. Carbonization within the tube bank 6 is prevented by the removal of entrained light products from the baffle tower reflux, during its passage through the drum 1. The pipes 17 discharge into the drum 1 at such an angle that the main circulation is not impeded, and by adjustment of this angle the boiling point of the 'gasoline produced may be controlled. Thus for gasoline containing 'an exceptionally high percentage of constitutents boiling under 212‹ F. the angle of discharge to the upward positive circulatory flow may vary from 0‹ to 45‹. For gasoline of ordinary quality a discharge angle of from 45‹ to 90‹ is preferred. The selective release of desired fractions from the reflux tower 23 is controlled by regulating the rate of fresh feed and a pressure valve 26 in the discharge pipe. The maximum dispersion of the adsorbent is ensured bv discharging, it into the still contents at the ,point of minimum surface tension, viz. the front end of the drum 1.
